Definitions

  • the invention relates to a connector for a photovoltaic arrangement, which has a plurality of photovoltaic modules each having a floating body, the connector being designed to mechanically connect at least two of the photovoltaic modules to one another, the connector having a base element and a plurality of coupling elements protruding laterally from the base element, wherein each of the coupling elements has a fastening means for fastening to one of the photovoltaic modules, and wherein the connector has at least one elastically deformable compensating element for enabling relative movements of photovoltaic modules connected to one another by the connector to one another.
  • the invention also relates to a photovoltaic system for producing a photovoltaic arrangement, with a plurality of photovoltaic modules, each of which has a floating body and at least one photovoltaic collector, in particular a solar cell or solar cell module, which can be arranged or arranged on the floating body, and with a plurality of the above-mentioned connectors through which Several photovoltaic modules or floating bodies can be connected to each other.
  • adjacent photovoltaic modules are connected to one another by at least one connector in such a way that relative movements of the photovoltaic modules to one another are made possible to a certain extent , without, for example, the distances between adjacent photovoltaic modules from each other exceeding a predetermined value.
  • the connection could also be ensured by rigid connectors, which firmly or rigidly connect the photovoltaic modules to one another, but then mechanical stresses could arise during operation due to the possibly large-area photovoltaic arrangement with a large number of photovoltaic modules.
  • a connector which has an elastically deformable compensating element, which enables the relative movements of the photovoltaic modules to one another. It is provided that the connector has a plurality of laterally projecting coupling elements, the coupling elements being connected to one another or to a base element of the connector by an elastically deformable compensating element in the form of an elastically deformable joint. This gives the connector itself an elasticity between the fastening points, which enables the relative movements of the photovoltaic modules. Depending on the design of the connector, larger or smaller relative movements can be made possible.
  • a similar photovoltaic arrangement is also from the published patent application, for example EP 3 709 506 A1 known, in which adjacent photovoltaic modules are connected to one another by a spring element. Also the disclosure document CN 111565008 A discloses a photovoltaic system designed for swimming with photovoltaic modules mechanically connected to one another, each of which has a floating body.
  • the disc-shaped ring element now has at least one free cut that extends in the circumferential direction of the ring element, i.e. a parallel or almost parallel to the outer edge and / or inner edge.
  • the free cut creates a breakthrough through the ring element in the axial extent, which reduces the material of the ring element and thus reduces its rigidity.
  • the outer edge is designed in particular to be attached to the coupling element or to the photovoltaic module and the inner edge is designed to be attached to the photovoltaic module or to the coupling element.
  • the compensating element thus forms a bearing plate that acts between the coupling element and the photovoltaic module and is elastically deformable.
  • the ring element has at least two free cuts which extend along the same circumferential lines of the ring element.
  • the Ring element theoretically has an infinite number of imaginary circumferential lines, i.e. lines that extend in the circumferential direction of the ring element and thus each form a closed (imaginary) ring, i.e. have no beginning and no end.
  • the circumferential lines run parallel or almost parallel or concentric or almost concentric to the outer edge or inner edge of the ring element. Because at least two of the cutouts extend along the same circumferential line of the ring element, they extend parallel/concentric or almost parallel/concentric to the outer edge or the inner edge of the ring element on the same circumference, which results in advantageous elasticities in the ring element.
  • At least two of the cutouts extend along different circumferential lines of the ring element.
  • two of the free cuts are, for example, radially spaced apart from one another in the ring element.
  • the free cuts can also run parallel or concentric to one another or at least in sections parallel or concentric to one another in the ring element in the circumferential direction.
  • the more free cuts there are on different circumferential lines the greater the deformability of the compensating element.
  • the position and dimensioning of the respective free cut not only determine the elastic force of the ring element as a whole, but also locally, so that an appropriate arrangement and design of the free cuts can lead to different elastic resistances of the ring element in different directions.
  • adjacent free cuts in the circumferential direction on the respective circumferential line end at a distance from one another to form an elastically deformable radial web of the ring element.
  • the radial web Seen in the circumferential direction, the radial web is designed to be many times smaller or shorter than the free cuts, so that the radial web holds the ring element together, the free cuts only briefly interrupt a circumferential line, and are therefore easily elastically deformable. This ensures a particularly high elasticity of the connector through the ring element.
  • radial webs of adjacent circumferential lines are arranged offset from one another in the circumferential direction. If several free cuts are formed on several circumferential lines, so that at least one, preferably at least two, three or more radial webs result on each circumferential line, the radial webs of adjacent circumferential lines are preferably offset from one another when viewed in the circumferential direction. As a result, force is never introduced or redirected through the ring element in a direct radial path from the outer edge to the inner edge or vice versa.
  • the advantageous design of the ring element ensures that lines of force inevitably arise in the circumferential direction of the ring element, which increases the spring and lever travel of the ring element and thus further improves the deformability of the ring element, without compromising structural safety with regard to the connection of the coupling element with the respective photovoltaic module.
  • the ring element is particularly preferably made of plastic, in particular thermoplastic elastomer, rubber and/or metal. Even if the material of the ring element itself has a relatively high coefficient of elasticity, the elasticity of the ring element is increased to the desired level by the advantageous cutout(s).
  • the coupling element has an opening for receiving the ring element in a section remote from the base part, the coupling element having at least one retaining web projecting into the opening for fastening the ring element, in particular for engaging in the groove of the ring element.
  • the ring element can thus be inserted into the opening of the coupling element and is locked or held therein in particular by the at least one retaining web, so that a positive connection between the coupling element and the ring element is ensured.
  • the coupling element preferably has a plurality of holding webs projecting into the opening, which are particularly preferably arranged evenly distributed over the circumference of the opening in order to ensure uniform force absorption over the circumference of the ring element or the opening.
  • the respective holding web has a section that projects radially into the opening and an axially projecting holding section at the end of the radially projecting section.
  • the holding section provides a rear grip seat for the ring element, which ensures a particularly strong, positive connection, since the holding section also acts in the radial direction and further makes it more difficult to detach the ring element from the coupling element.
  • the ring element has at least one axial receptacle that can be assigned or assigned to the holding section and into which the holding section can be inserted.
  • the opening of the coupling element is designed to be closed on the circumference, so that the opening has a closed outer edge which completely surrounds the ring element on its outer edge. This ensures an advantageous introduction and transmission of force.
  • the coupling element preferably has a plurality of retaining webs or a retaining web extending over the entire circumference of the opening.
  • the multiple retaining webs make it possible to ensure rotation protection between the ring element and the coupling element, and the holding web is maximized in the axial direction by the continuous retaining web or which extends over the entire circumference.
  • the inner edge of the ring element has a receiving opening with a contour that deviates from a circle, into which a fastening bolt of one of the photovoltaic modules can be inserted.
  • the inner edge of the ring element which radially delimits the receiving opening, therefore has a contour that deviates from a circle, which forms a rotation lock with the fastening bolt when the fastening bolt inserted into the receiving opening has an outer contour corresponding to the receiving opening. This rotation lock prevents the fastening bolt from rotating within the ring element or the ring element relative to the fastening bolt.
  • the contour of the receiving opening is oval-shaped.
  • the cross section of the fastening bolt is preferably oval-shaped.
  • the oval design of the receiving opening and fastening bolts ensures advantageous power transmission and secure anti-twist protection.
  • the contours of the receiving opening and fastening bolts are polygonal, in particular polygonal, in order to form the positive anti-twist device.
  • the coupling element is Y-shaped, with a main arm carrying the ring element and with two base arms extending from the main arm at an end remote from the ring element.
  • the coupling element thus has three struts which converge at a connection point or which are connected to one another at one of their ends - seen in the longitudinal extent.
  • the coupling element is designed in one piece, so that a high level of robustness and dimensional stability of the coupling element is guaranteed.
  • the coupling element is particularly preferred designed as a lightweight component that has a support structure made of stiffening ribs, which ensures a sufficiently high level of robustness or rigidity of the coupling element despite low material expenditure and therefore low manufacturing costs and material costs.
  • the coupling element itself is designed in such a way that it is not or only slightly deformed elastically in response to the forces expected during operation that could act on the coupling element in the photovoltaic arrangement. This ensures that the elastic deformation and thus the compensating movements are at least essentially ensured solely by the ring element. As a result, the elasticity of the photovoltaic arrangement can be specifically adjusted and influenced by the connection of the connector using the ring element.
  • the coupling element is designed as an injection-molded part, preferably as a plastic or aluminum injection-molded part.
  • all coupling elements forming the base element of the connector are each designed the same.
  • the connector is therefore manufactured using identical parts or using identically designed coupling elements. This further reduces manufacturing costs and further simplifies assembly because incorrect assembly is avoided.
  • the base arms of the respective coupling element preferably enclose an angle of 90° or almost 90° between them. This gives the base element a square or at least rectangular contour, which ensures that even high forces are reliably transmitted. Since the base element is formed by the base arms, it results that the base element itself is annular and has a central opening or recess. This recess can be used, for example, to attach an anchor for the floating photovoltaic system to the connector. For this purpose, for example, the anchor can be held with a loop on one of the base arms or on the base element. It is also conceivable to insert an insert into the receptacle of the base element, which rests partially on the base element and to which the anchor can be attached.
  • the connector has more than 4, in particular 5 or 6, coupling elements.
  • the angle that is included between the base arms of the respective coupling element can also be determined differently depending on the type and number of coupling elements present in the connector, with the base arms of the respective coupling element in particular enclosing an angle of 30° to 120°.
  • the base arms are designed such that, when assembled, they form a base element with a continuous surface, i.e. form an opening-free base element. This further increases the robustness of the connector.
  • each photovoltaic module has at least one, preferably several, fastening bolts distributed over the circumference of the respective photovoltaic module, which can each be inserted into a receiving opening of a ring element of a connector.
  • the fastening bolt or bolts are attached to the floating body of the respective photovoltaic module.
  • the Floating bodies or photovoltaic modules have a rectangular, in particular square, basic shape, so that a fastening bolt is arranged at each of the four corners of the photovoltaic module or the floating body.
  • the recess has a receiving section for receiving the securing projection of the coupling element in order to also limit the movement play when the coupling element is displaced laterally relative to the fastening bolt, i.e. in the radial direction in addition to or alternatively to the circumferential direction. This ensures that the load on the ring element is limited mechanically by the photovoltaic module, in particular by the respective floating body, both in terms of possible torsion and in terms of lateral displacement, so that overloading of the ring element is safely and permanently prevented.
  • the recess of the photovoltaic module in particular of the floating body, has in particular a contour which at least essentially corresponds to the outer contour of the coupling element in the area of the main arm, the clear width the recess is larger than the outer contour of the main arm in order to limit or proceed to the predetermined play of the coupling element relative to the photovoltaic module.
  • the photovoltaic arrangement according to the invention with the features of claim 26 is characterized by the inventive design of the connector or connectors. This results in the advantages mentioned above.
  • the photovoltaic arrangement has a plurality of floating or designed to float photovoltaic modules, as well as a plurality of connectors according to the invention, by means of which adjacent photovoltaic modules are connected to one another.
  • the photovoltaic arrangement according to the invention is particularly preferably produced by the photovoltaic system according to the invention.

  • the photovoltaic arrangement 1 has several photovoltaic modules 2, which are designed the same.
  • Each photovoltaic module 2 has a floating body 3, which is designed in several parts.
  • each floating body 3 has an upper shell 4 and a lower shell 5.
  • Upper shell 4 and lower shell 5 are each trough-shaped and arranged next to each other in such a way that they enclose a cavity between them.
  • the upper shell 4 and lower shell 5 are only assembled on site during assembly and have connecting means that allow the upper shell 4 and lower shell 5 to be tightly connected.
  • the cavity created gives the floating bodies 3 sufficient buoyancy so that they can float on the water and not sink.
  • the upper shell 4 and lower shell 5 can be stacked in such a way that they partially lie inside one another, whereby a large number of upper shells 4 and lower shells 5 can be transported and provided in a small space.
  • FIG 2 shows the middle connector 8 in a simplified top view Figure 1 .
  • the connector 8 has four coupling elements 9, which are of the same design and are designed for attachment to the photovoltaic modules 2.

  • the main arms 11 each have a circular opening 14.
  • the main arm 11 is widened, the widening running parallel to the circular shape of the opening 14, so that a retaining ring 15 is formed in the main arm 11 of the respective coupling element 9, the retaining ring 15 being formed coaxially with the opening 14.
  • Figures 3A and 3B show one of the coupling elements 9 of the connector 8 in a top view and in a bottom view.
  • the base arms 12, 13 are of equal length, with the base arm 12 having a recess 16 on its underside and the base arms 13 having a recess 17 on its upper side.

  • the screw openings 18 are designed such that a thread can be cut into at least one of the screw openings 18 by the screw.
  • a screw thread is inserted or already cut into one of the screw openings 18 of one of the base arms 12, 13.
  • Figure 3B shows that the coupling element 9 in the area of the opening 14 has a holding web 27 which projects radially into the opening 14 and extends over the entire circumference of the opening 14.
  • the holding web 27 has a height that corresponds in particular to the width of the groove 26.
  • the retaining web 27 engages in a form-fitting manner in the groove 26 of the ring element 22, so that the ring element 22 is fastened to the coupling element 9 in a form-fitting manner in the axial direction.
